List of Possible Drupal Spammers

Caution: These IP lists are auto generated and might not all be spammers, we do not recommend using this as a blanket black list.

Our Preferred Solution

We find the best way to block these spambots is to cross reference this list with your server logs and deny the IP ranges of the worst offenders via Cpanel.
For Drupal sites implement the CAPTCHA + Riddler modules and use a skill testing question specific to your site's niche.
